A trichobezoar refers to a mass, primarily composed of hair and food, that accumulates within the stomach.
Understanding Trichobezoars
Based on information from Pediatric Gastrointestinal and Liver Disease (Fourth Edition), 2011, a trichobezoar is defined as:
- Composition: A compacted mass consisting of hair and food.
- Location: Typically forms and resides within the stomach.
These masses can grow significantly over time as more ingested hair and food particles are added.
Who is Affected?
Trichobezoars are often observed in specific populations:
- They are frequently found in young females and children.
This demographic link is often associated with certain behavioral conditions, though the underlying causes can vary.
Potential Symptoms
The presence of a trichobezoar can lead to noticeable symptoms. According to the reference, it can cause:
- A foul-smelling odor.
- Halitosis (bad breath).
Other symptoms, such as abdominal pain, nausea, vomiting, or weight loss, may also occur as the mass grows and obstructs the digestive tract, though these specific symptoms are not detailed in the provided reference.
How They Form
Trichobezoars develop when a person ingests hair, a behavior known as trichophagia. Humans cannot digest hair, so swallowed strands accumulate over time, mixing with food particles to form a dense mass. This behavior is often linked to trichotillomania, a disorder characterized by the urge to pull out one's hair.
Here is a summary of the key features:
| Feature | Description |
|---|---|
| Definition | Mass of hair and food in the stomach |
| Composition | Hair and food |
| Location | Stomach |
| Demographics | Often young females and children |
| Symptoms | Foul-smelling odor, halitosis |
Understanding trichobezoars is important for recognizing the potential health issues associated with hair ingestion and seeking appropriate medical evaluation if symptoms arise.
